Hi Folks!
I'm asking for a friend of mine - a new owner of this model.
1600 motor, Weber carbs, points ignition, manual choke.
The car refuses to start on the self starter when warm. If pushed
it'll start right away. He's changed the starter motor to no avail.
Any ideas?
Bill, DK

Dodgy battery, possibly. When cranking the engine there's not enough
oomph to give a spark. Easily tested by borrowing another battery or
trying a jump start.

Another possibility is flooding carburettor (I had the same problem with
a Morris which turned out to be that). Check the float and needle valve.

If it is none of those, suspect the condenser, the coil, or the
distributor cap. Any of those could give hot start problems.

Can we please get one thing straight before we all pile in. Does refuse to
start on the self starter mean that the starter motor doesn't turn the
engine or that the starter motor turns the engine at normal cranking speed
but the engine doesn't fire? Or somewhere in between the two?

That's easy to answer, YES.

I'll clarify:
Engine warm (stopped 15 minutes ago).
Get in car.
Key in.
Ignition on.
Key turned.
Starter relay engages.
Starter motor turns.
Starter cogs engage.
Engine turns at a reasonable speed.
Engine refuses to start.

Finish the ice cream which was the reason for stopping.
Ask friendly passers-by to give a push ( at the back of the car ).
Get in car.
Key in.
Ignition on.
Passers-by push ( on the back of the car )
Disengage clutch.
Engage second gear.
Engage clutch.
Engine turns.
Engine starts.

Sorry if the vagueness of my previous mail confused you.
Thankyou all for the suggestions - keep them coming.

Does it turn over slower when hot? If not you can assume the starter's ok.
I'd go for the mixture being wrong. But obviously check the voltage at the
coil to make sure it is the same as at the battery when cranking - or the
correct amount if a cold start coil.

No, it didn't confuse us, just didn't give us enough to work on. Now we
have, well almost but I'll come to that later, and the really important bit
is the ice cream that you finished before getting the push start. What I
reckon happened is that for some reason the engine had flooded (petrol level
in the float chamber too high?) but by the time you finished the ice cream
enough of the petrol had evaporated to enable the plugs, now getting the
full current from the battery unencumbered by the starter motor, to fire the
mixture. What you didn't tell us was whether the car had been parked facing
up hill - this can make matters worse if the float chamber needle valve is
prone to leak and over fill the chamber ( if the engine layout is as I think
it is). If this happens again, try slowly pressing the accelerator pedal
right to the floor and working the starter again, that way you should get
enough air through to dilute the mixture to something the plugs can fire.
Don't stamp on the pedal or the accelerator pump(s) will only make matters
temporarily worse.

Good luck

The ignition is controlled by a relay that requires _either_ starter
current, or oil pressure, before it will power the ignition. If this
isn't working, it might not fire when you expect. Does it fire if you
crank it until the oil pressure warning light goes out? (the usual way
this failure manifests itself).

If it works on oil pressure that should effectively rule out push starts -
except by several very fit people. . .
